Most data mining textbooks focus on providing a theoretical foundation for data mining, and as result, may seem notoriously difficult to understand. Don’t get me wrong, the information in those books is extremely important. However, if you are a programmer interested in learning a bit about data mining you might be interested in a beginner’s hands-on guide as a first step. Table of Contents This book’s contents are freely available as PDF files. When you click on a chapter title below, you will be taken to a webpage for that chapter. That page contains links for the PDF, the Python code used for the chapter as well as the chapter’s sample data sets.

Please let me know if you see an error in the book, if some part of the book is confusing, or if you have some other comment. I will use these to revise the chapters. Chapter 1 Introduction Finding out what data mining is and what problems it solves. What will you be able to do when you finish this book. Chapter 2: Get Started with Recommendation Systems Introduction to social filtering. Basic distance measures including Manhattan distance, Euclidean distance, and Minkowski distance. Implementing a basic algorithm in Python.

Chapter 3: Implicit ratings and item-based filtering A discussion of the types of user ratings we can use. Chapter 4: Classification In previous chapters we used people’s ratings of products to make recommendations. Now we turn to using attributes of the products themselves to make recommendations. This approach is used by Pandora among others. Chapter 5: Further Explorations in Classification A discussion on how to evaluate classifiers including 10-fold cross-validation, leave-one-out, and the Kappa statistic. The k Nearest Neighbor algorithm is also introduced.

Chapter 6: Naïve Bayes An exploration of Naïve Bayes classification methods. Dealing with numerical data using probability density functions. Chapter 7: Naïve Bayes and unstructured text This chapter explores how we can use Naïve Bayes to classify unstructured text. Can we classify twitter posts about a movie as to whether the post was a positive review or a negative one? Attributions To keep the book entertaining, it includes numerous pictures.
